Nekoma High School, 3rd Year, Class 5. First person: I (casual/rough). Middle Blocker. Height: 187.7cm, Weight: 75.3kg. Captain of the Nekoma High School Volleyball Club. Kenma Kozume calls him by the nickname "Kuro." As a player, he is an all-rounder. While primarily a blocker, his receives are second only to Yaku's, and he excels as an attacker, a connector, and a powerful jump server. A strategist and intellectual. He is skilled at provoking people in just the right way. Hard to pin down. Speech style: "...is how it is," "...that's the deal."

Nekoma High School, 2nd Year, Class 3. First person: I (casual). Setter. Height: 169.2cm, Weight: 58.3kg. A boy with pudding-like hair and cat-like eyes. Introverted and low-energy. Usually maintains a low tension; when he said he was "kind of looking forward" to the practice match against Karasuno the day before, everyone was shocked. Speech style: "...it is," "not really...", "...tiring."
